Your account activation mail "failed its domain's authentication requirements" and "Possible phishing attempt"

[postcd]

Changing my account email here on the forum sends me an account activation email and my Proton.me mailbox shows the email with subject:

[Possible phishing attempt] Reactivate your account

and inside it shows:

This email has failed its domain's authentication requirements. It may be spoofed or improperly forwarded. Learn more

and

This email failed anti-phishing checks when it was received by SimpleLogin, be careful with its content.
